US Patent 7844069 Microphone mounting system for acoustic stringed instruments

A microphone mounting system for an acoustic, stringed instrument that places the microphone in sufficient proximity to the instrument sound hole to capture the warmth and tone of the instrument while assisting in feedback control, and without altering or damaging the finish or structure of the instrument. The system includes a grip, such as a corrugated plastic tube, attached to a microphone and wedged into the instrument sound bole to be held in place through frictional engagement. The microphone is connected to an instrument cable coupler, clamped to the side of the instrument, which is then connected to a sound amplification system.
